13.1 Exterior Hull and Deck
Hull Cleaning-Below The Water Line
Your Monterey hull is manufactured using state-of-
the-art materials and processes. A layer of super
tough, Ashland “AME” Resin with high density and
superior adhesion properties provides an excep-
tionally effective barrier to osmotic blistering.
Osmosis is caused by a chemical reaction between
water and substances in the hull laminate below
the waterline. If water breaches the exterior
gelcoat and barrier layer, it can react with the
chemical components in the laminate creating
acidic substances. These substances create pres-
sure behind the gelcoat which causes blisters.
SANDbLASTING THE HULL bOTTOM WILL
DAMAGE THE fIbERGLASS. USE A fIbERGLASS
WAX REMOVER AND SAND TO SCUff THE
GELCOAT SURfACE. THE INSTRUCTIONS AND
RECOMMENDATIONS Of THE bARRIER COATING
AND ANTIfOULING PAINT MANUfACTURERS
SHOULD bE fOLLOWED EXACTLY.
bARRIER COATINGS AND bOTTOM PAINT SHOULD
bE APPLIED ONLY bY QUALIfIED MARINE
PROfESSIONALS IN A bOAT YARD OR DEALERSHIP
THAT SPECIALIZES IN THEIR APPLICATION. USE
ONLY STANDARD, HIGH QUALITY ANTIfOULING
PAINTS AND bARRIER COATINGS fROM NAME
bRAND MANUfACTURES SUCH AS INTERLUX
AND PETTIT.
DO NOT ALLOW THE HULL ANTIfOULING PAINT TO
CONTACT THE OUTDRIVE. MOST ANTIfOULING
PAINTS DESIGNED fOR HULL bOTTOMS CONTAIN
COPPER AND CAN CAUSE SEVERE GALVANIC
CORROSION DAMAGE TO THE OUTDRIVE UNIT.
USE ONLY ANTIfOULING PAINT DESIGNED fOR
OUTDRIVES AND OUTbOARD MOTORS. ALWAYS
LEAVE A ONE INCH bARRIER bETWEEN THE HULL
bOTTOM PAINT AND OUTDRIVE.
Most bottom paints require some maintenance.
Proper maintenance is especially important when
the boat is in saltwater and not used for extended
periods or after dry storage. If the hull bottom
has been painted with antifouling paint, contact
your dealer for the recommended maintenance
procedures.

Sacrificial Anodes
Sacrificial anodes are installed on the inboard
engines’ freshwater cooling system, outdrives
and on the transom. The transom anode is con-
nected to the bonding system and protects the
trim tab hinges, metal thru-hull fittings and other
underwater hardware that is bonded. Additional
anodes should be installed on the trim tab planes
if the boat is to be left in the water, if not already
installed.
The anodes are less noble than copper based
alloys, aluminum and stainless steel. They will
deteriorate first, protecting the more noble engine
and underwater hardware against galvanic cor-
rosion. Anodes should be checked monthly and
changed when they are 75% of their original size.
Additionally, anodes that are subjected to frequent
wetting and drying require periodic scraping with
sandpaper to remove scale and oxidation to main-
tain their effectiveness.
When replacing the anodes, make sure the contact
surfaces are clean, shiny metal and free of paint
and corrosion. Never paint over the anode. The
bonding system should be inspected by a quali-
fied marine electrician once a year to make sure
all connections are sound and there is continuity
throughout the system.
Boats stored in saltwater will normally need to
have the anodes replaced every 6 months to
one year. Anodes requiring replacement more
frequently may indicate a stray current problem
within the boat or at the slip or marina. Anodes
that do not need to be replaced after one year may
not be providing the proper protection. Loose or
